At age 69, now - I began in the world of RC Flight over 20 years ago re my son, Christian, then a young teen. I took my time with the PT 40 kit. As it turned out - it was an easy build and the plane was perfectly balanced without me "balancing it." It could glide, re a dead stick," for a mile, if need be. It made many flights before I gave it away - moving up to "bottom wing," kits.
